Hello Ailing, I have read several of your posts, and I had written in an earlier post that maybe you should look for a Crohn's support group near you. I mentioned that you could not only get alot of your questions answered but you will meet lots of other people who are going through the same thing you are.
You also mention that you are having problems with your Mother, husband and now your son, so I will make another suggestion that you might want to consider is to talk to a counsellor, they can maybe help you with some of the difficult decisions that you are trying to make. A counsellor may also be able to help you with dealing with some of the problems you seem to facing with your son. Your posts are filled with alot of stress and talking to professional people may help you deal with that too.
These are just a few suggestions for you since your posts come across that you are needing more help than you are Best of luck to you.
